AI Technical Summary

Benefits of technology

The present invention provides a structure for an RGB-IR sensor that can efficiently recover infrared images and obtain accurate depth information of recognized objects. This results in clearer and accurate 3D image signals. The technical effect of this invention is improved image quality for both visible light and infrared images.

Problems solved by technology

Therefore, if interpolation is performed using the loose coupled IR pixels only, a problem occurs in that interpolation accuracy and efficiency are more deteriorated than the case where at least one or more tight coupled IR pixels exist.

Abstract

The present invention relates to an RGB-IR sensor, and a method and an apparatus for obtaining a 3D image by using the same. The RGB-IR sensor according to the present invention comprises: a first pixel basic unit including one of each of R, G, B and IR pixels; and a second pixel basic unit in which the R, G, B and IR pixels are arranged in a different order from those in the first pixel basic unit, wherein the RGB-IR sensor is comprised by alternately arranging the first pixel basic unit and the second pixel basic unit in a horizontal direction, and wherein R, G, B and IR pixel arrangements in the first pixel basic unit and the second pixel basic unit are determined so that the position of IR-pixels in the RGB-IR sensor are not equidistance apart from each other.

Description

TECHNICAL FIELD[0001]The present invention relates to an RGB-IR sensor, and a method and an apparatus for obtaining a 3D image by using the same.BACKGROUND ART[0002]Recently, various techniques and products for obtaining a 3D image from a recognized object have been developed. For example, a TOF (Time Of Flight) system is to obtain a 3D image from a distance or depth between a camera and a recognized object, which is measured using a temporal difference between a light emission time for irradiating light to the recognized object and a light receiving time of light reflected from the recognized object. Also, a structure light system is to obtain a 3D image from a depth of a recognized object, which is measured by emitting patterned infrared structured light to the recognized object and analyzing a pattern of infrared rays received from the recognized object.[0003]In this regard, although two or more visible light images may be used to obtain 3D depth information, a system, which uses...
